LAMP.

SPEGECATION forming part of Letters Patent No. 323,037, dated July 28,1885.

Application llcd April 6, 1885. (No modeLl To @ZZ whom it may concern.-

Be it known that I, THOMAS HIPWELL, of Astoria., in the count;v ofQueens and State-of New York, haveinveuted an Improvement in Lamps, ofwhich the following is a specilication.

My present invention is made for lessening the expense of constructingArgand lamps,v

2o In the application of James H. lVhite and Thomas Hipwell, No.129,836, filed April 26,`

1884, a lamp is shown containing all the features of the presentinvention, except those that are herein especially pointed out; and a 25 reference is hereby made to the said application for a description ofall those parts not here specifically set forth-such as the wiekraisingdevice, the reservoir Wick-tubes, airtube, annular ratchet-cores,gallery, removable deliector, and spring chimney-holder.

Lamps of this character containing a largeY Argand wick are extensivelyused upon chan deliers and brackets, and they have to be removedtherefrom for cleaning and trimming. One feature of my said inventionrelates to a skeleton socket and foot-piece applied at the lower end ofthe air-tube g, such skeletonsocket being made of two metal plates, g,each of which is provided with a central slot at 10 4o and twoprojecting feet at 1l, and the central cross-bar is notched, the notchin one piece being at the top ofthe cross-bar and the notch inthe otherpiece at the bottom of the crossbar, so that these twocrossbars,whenplaced 4 5 together,interlock,and with the other portionsform a skeletonsocket and foot-piece that is passed up into the lowerend of the air-tube g and secured therein. ThisV foot-piece, projectingat the bottom of the lamp outside the 5o lower end of the air-tube g,forms a support for holding up the lamp while being trimmed or filled,and the air can pass easily into the air-tube, hence the flame can beadjusted be fore placing the lamp on the chandelier, and the skeletonsocket formed by the notched plates within the air-tube receives theplug or stud h of the chandelier or bracket, by which stud the lamp issupported when in use, and from which it is easily removed for iillingand trimming, andthe skeleton socket is not liable to adhere to the plugin consequence of rust or any accumulation of foreign matter.

At the upper end of the wick-tube!) the dame-spreader or button n issupported by the legs Z',which project downwardly from said 65 button nand pass into the air-tube g,and rest upon an inward-projecting rib, 14,that is bent in the sheet metal of such air-tube g. The legs are made oftwo crossing plates cut out in the form represented in Fig. 4. One platehas'a central slot cut from the upper end of the body downwardly, andthe other plate has a central slot cut from the lower end of the bodyupwardly, and these plates are interlocked across each other by thecentral slot of 7 5 one plate receiving the sheet metal of the otherplate. At the upper ends of these plates are projecting ears 15,that arepassed through radial slots in the central portion of the iiamespreadern, and these ears are turned over and clinched, so as to hold theflame-spreader or button firmly to the supports formed by the crossingplates and legs lf. When these legs are passed down into the air-tube y,and their lower ends rest upon the rib 14, the iiame- 85 spreader willbe held in its proper position in relation to the upper end of the wick,and the legs and support to the flame-spreader, being comparatively ofthin sheet metal and standing edgewise to the current of air pass- 9oing up the tube g, offer but little resistance to the air, and suchsupport is kept cool., and but little heat is conducted from the buttonto the lamp. These legs, being spring metal, accommodate themselves toany inequalities in the size of the air-tube. In iilling lamps of thischaracter it is often difficult to determine when the necessary quantityof oil has been supplied.

Lamps have been'made containing a lioat 10o and a stem, so that thequantity of oil inthe lamp may be indicated by the rising of the stem ofthe float. It such float und stem Were applied to a lamp ofthe presentconstruction7 the stem projecting above the metal annular ratehetcovert, such stem would interfere with the polishing and finishing of thelmnp. To avoid this I make use of a wire cage, r', inside the reservoir,the saine being formed by preference of two Wire loops Crossing eachother and soldered :Lt their upper ends to the metallic portion of thelump, and containing between them a, cylindrical float, 1*, prefere` blyof cork, with a central depression in the upper su rfztce, und there is:t hole through the metal of the lmnp nid in line with the center of theoztt for the reception of the stem s2; but this stem is not put in placeuntil after the body of the lmnp has been put together and polished andfinished, after which such stem is thrust through the hole in the metaland driven into the cork, the central depression in such cork serving toguide the end of the stem, and I make the stem of wire with the endportion eorrugatt-Jd7 so as to prevent the stein being pulled out ofthecork Hout accidentally. It is to be understood that the edge und floatare put into place before the lump-reservoir is put together.

I do not herein ley claim to the float, cage, und stem hereinbeforedescribed.

I claim as my invention- 1. The conibination,with the wick-tube andair-tube in an Argand lmnp, of a Humespreader or button, n, twolongitudinally-slotted, crossing, and interlocking plates, each havinglegs Z extending down into the airtube g, and ears l5 at their upperends passing through niortises in the flame-spreader and clinched,substantially as set forth.

2. The combination, with an Argand lamp, of the crossing andinterlocking plates with slots forming a. skeleton socket fitted withinthe air-tnbe, andhaving projecting foot-pieces below the lower end ofsuch airvtube, and the plug h iitted Within the socket-piece,substmrtiell y as set forth.
